- plastically deformable rigid polyurethane foams installed in the automotive interior which are usually used as trim parts in the roof area, so-called headliners, are complex. So they must have a certain rigidity and must not emit disturbing substances that lead, for example, to odor.
- a particularly important function of the headliner is its contribution to the acoustics. Here it is a particular task to reduce airborne noise, the so-called airborne sound.
- the quality of these headliner properties depends critically on the properties of the plastic used deformable rigid polyurethane foams. For good airborne sound absorption, rigid polyurethane foams with the highest possible air permeability are desirable.
- the currently known plastically deformable rigid polyurethane foams meet these requirements only limited.
- the soundproofing of a plastically deformable rigid polyurethane foam / headliner depends to a great extent on its air permeability.
- roof skins of rigid polyurethane foams with improved air permeability better dampen the airborne sound.
- Improved air permeability and thus also improved sound insulation can be achieved by "needling" the thermo-formable rigid polyurethane foams / headliner, which inserts needles into the finished foam / headliner, thus improving the air permeability of the foam / headliner and thus the soundproofing.
- this method has the disadvantage that a further working step is necessary for the production of the sound-absorbing rigid polyurethane foams.
- the object of the present invention was therefore to provide a process for the production of plastically deformable rigid polyurethane foams, which have an increased air permeability and thus excellent sound damping, without further process steps, such as needles, are necessary.
